Hey all - I am currently happily supping my way through some Woodfordes kits by way of reintroduction to the wonders of home brewing (they're not bad at all) but I'm getting stuff together to go AG.

Now: I want to use a large ally stock pot as my kettle. 60/70 litres in size, as I think I'll end up making seven and a half gallon batches, or bigger. What worries me is that with a stock pot which has a diameter or 50cm or so, do you suffer from large amounts of boil-off? And if so, would a lid with a couple of holes to let the steam escape be a good idea or not?

Also, I'm planning on boiling on my gas hob. I have a double range thingy, and on one side of it is a wok burner - two rings in one. Anyone else use this kind of setup, or should I really be thinking of fitting elements or using a big dedicated burner outside?

All advice greatfully received :thumb:
 
Mike,

On the point about using the cooker to heat the pot, I have heard of people having issues where they get incompleat combustion due to not enough air getting under the large pot. Watch out for a yellow flame as that means Carbon Monoxide, which aint good! Lifting the pot somehow can allow sufficient air in...

Cheers

I use a 60 litre aluminium pot on a gas range, covering one large and one small burner. I have never had any problem with incomplete combustion or yellow flames.

Mine has a lid within a lid, if that makes any sense, something like a 16" lid with an 8" middle lid, so I boil for the first 75 mins with the middle out and the last 15 with lid completely off, and expect to lose about 6-7 litres that way, so if you leave your lid partly covering the pot to start with it should be fine.
